Human babies get these bacterial helpers from their moms.When a baby is born，some of the bacteria in the mother move into the baby’s body.Growing babies get additional “good” bacteria from the milk their mothers produce.And it turns out the bacteria might play an important role in regulating weight just six years later.

　　So how could these bacteria affect weight？The researchers still haven’t tested that question，but future tests might lead to an answer.
